People of Stockton, California! Do not play Grand Theft Auto IV! Do not!! It's turning local residents batty. According to the Stockton Record:

"My son Peter was never really aggressive, but once he got into video games, 'GTA' being one of them, he started to push, hit, talk back, and just become a different person," said Stockton parent Greg Within, 46.

Stockton's Mark Wellis, 19, said he was involved in an altercation a week after he purchased "Grand Theft Auto IV." At the time he noticed that he had become less sensitive to violence.

Wellis doesn't completely blame the game for his violence, but it did affect him.
